⚾ IMPROVE YOUR PITCH VELOCITY AND STRENGTH – Throwing velocity is one of the most prized characteristics of the competitive baseball pitcher. Each additional 1-mph increase in ball velocity decreases the batter’s time to react by about four milliseconds (roughly 1%). It may be small, however, the difference between a hit and a strike is measured in milliseconds. That’s where training with our weighted baseball fits in, to help you get more strikeouts!
⚾ EXTENDED WEIGHT RANGE AND MORE BALLS – This set contains 8 practice baseballs that range from 3oz to 14oz. No other competitors offer you this much flexibility. Create a training program that’s perfect for you or your students. Start increasing your fastball speed as soon as you receive them!
